Eye protection desk lamp and brightness adjusting method thereof

Abstract

The invention relates to the technical field of lighting, in particular to an eye protection desk lamp and a brightness adjusting method thereof. The eye protecting desk lamp comprises a lamp source, a lamp source control device, a camera and an image processing device, wherein the lamp source is connected with the lamp source control device, the lamp source control device is connected with the image processing device, the camera is connected with the image processing device, and the camera is provided with a detecting device used for detecting the eye positions and an image collecting device used for collecting the characteristics of the eyes. According to the eye protection desk lamp and the brightness adjusting method thereof, when the situation that the eyes directly see the strong light lamp source is judged through the camera and the image processing device, the brightness of the lamp source is adjusted automatically and quickly, the lamp source is made to be more tender and darker, and therefore the effect of protecting the eyes is achieved.

[0002] Eye protection desk lamp is a relatively mainstream product in the market, and it is also a trend in the desk lamp market. Consumers begin to pay attention to eye health in addition to lighting. At present, eye protection desk lamp mainly includes detecting whether the sitting posture is correct, and automatically adjusting the light intensity according to the external environment. Weak, with mainstream properties such as no flicker and high display index, but when the user looks directly at the light source of the desk lamp, there will be strong light hitting the eyes directly. When the brightness of the light source is extremely high or the brightness difference between the background and the center of the field of view is large , will produce glare, too strong light will also cause glare and damage to the eyes. At present, to solve direct glare, most of them use secondary optics to limit the angle of light to ensure that the eyes cannot directly look at the light source outside a certain angle, and there is no way to avoid unconsciousness. Or accidents that cause glare and glare caused by visible light sources in the eyes
